Wow, a hundred times slower, and I was complaining about 5 times!

Here is my little test file:
#version 3.7;

global_settings
{
    assumed_gamma 1
    noise_generator 2
}
background
{
    color srgb <0, 0, 0>
}

union
{
    #for (I, -25, 25, 1)
        cylinder
        {
            <-20, 0, 0>, <20, 0, I>, 0.01
        }
    #end
    pigment
    {
        color srgb<1, 1, 1>
    }
}

light_source
{
    <25, 8, 0>, rgb<1, 1, 1>
}

camera
{
   location <25, 8, 0>
   right <image_width / image_height, 0, 0>
   look_at <12, 0, 0>
}

Cheers
Ton
